IMPROVEMENT IN PATTERNS FOR CASTING STOVE-LEG ATTACHMENTS.

Specification forming part of Letters Patent No. 209,811, dated November12, 1878; application filed March 2, 1878. 1

To all whom it may concern:-

Be it known that I, Hosnn ll. HUNTLEY, of Quincy, in the county of Adamsand State of Illinois, have invented anewand valuable Improvement inPatterns for Oastin g Stove-Leg Attachments; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings,making a part of this specification, and to the lettersand figures of reference marked thereon.

Figure 1 represents a sectional view of a stove-leg as it is applied tothe attachmentlug. Fig. 2 is a sectional view of the pattern of theattachment-lug in the drag. Fig. 3is a sectional view of the drag,showing the curved branch of the pattern partially detached. Fig. 4 is aperspective view of the curved branch of the pattern.

This invention has relation to means for casting attachment-1n gs forstovclegs, evaporating-pans, sugar-boilers, and the like.

The nature of the invention consists in the construction and novelarrangement of a pattern for casting attachment-lugs for the legs ofstoves and other heavy articles, said pattern having an upright lngbranch and a separate detachable curved branch, as will be hereinaftermore fully set forth.

In the annexed drawings, the letter A designates the bottom of a stove;B, the horizontal'arm of the stove-leg; (J, the eye-lug upon thestove-bottom, and D the key which confines the leg to the stove. Theeye-lug (l is triangular in its general form, and consists of an uprightpyramidal part, a, and a curved portion, b, diminishing in size from itsconnection with the plate A to its point of union with the uprightportion. The curved surfaces of the portion 1) are regular arcs ofcirclcs, as'shown in Fig. 3.-

The pattern E, from which the bottom plate having the attachment-lug iscast, is formed in two parts.

The upright wedge-form projection to, which serves to prepare 'the moldfor the east branch or of the lug O, is made entire with the plateportion A of the pattern, and is provided at its lower end with, anattachment notch or scat, e.

The curved branch I) of the pattern, which forms that portion of themold in which the curved branch I) of the lug is cast, is detachable andof a circular or arc-shaped tapering form. Its lower end is formed witha projection, is, which engages with the notch e of the projection a. ofthe pattern; and its upper end is provided with a stud, s, which passesthrough an aperture, t, in the plate portion A of the l'iattern.

The two portions of the pattern being put together in the mannerindicated, it is sunk in the sand of the drag in the usual manner toform the mold for the plate and lug. After the sand has been packed theplate portion A of the pattern is detached upward, leaving the curvedbranch I), which is afterward removed by a curved motion, the projection8 serving as a handle.

Upon the plate portion of the pattern a smaller projection, 12, isformed in rear of the aperture t. hen the curved branch of the patternhas been removed the mold is ready. Molten metal is then, poured in, andthe eyelug and stove-bottom cast in one piece.

In line with the lug is an angular catch, t, cast in the mold formed bythe small lug v of the pattern, the function of which will be hereinafter explained.

The under side of the horizontal arm B of the leg is made with a dishedrecess, a, at the bottom of which is a slot, 2, of suflicient size toreceive the eye-lug; and it is provided with an angular recess, r,designed to receive the catch it upon the stove-plate A. This arm orplate is cast with the leg complete, and upon coming from the mold isready for use.

The dish upon the under side of the leg branch or rm B greatlyfacilitates the attaehment of the leg to the stove, as it directs theeye-lug accurately to the opening of the slot 17. The bottom of thestove not being visible, this construction of the leg-bran ch or armsaves considerable time and labor. The leg being in position on thestove-bottom a triangular key, D, of the same conformation as the eye oflug G, is forced into the said eye, and offectually secures the leg tothe stove.

It is evident that this device is applicable to evaporating-pans,sugar-boilers, and other metal vessels, and is of equal advantage.

What I claim as new, and desire to secure by hereunto subscribed my namein the presence Letters Patent, isi of two witnesses.
